I've layed SOD during the fall before and have never experienced this. I layed some SOD on Saturday and began immediately watering it per the distributors instructions. I noticed yesterday that my seems have began to brown / yellow a bit. Furthermore, these areas including some areas of the middle of rolls simply pull out as easy as a weed after a hard rain. I assumed it was overwatering, but I don't know. The SOD setting is moist and the top soil beneath is moist. I can see root growth, but am concerned about the easy areas of pull up. Most of the rest of the grass is set and appears to be fine. -Could this be from overwatering? -Can these areas recover with backing up on the watering?
